I came across a company call Stellar Rigs who claim to be selling some pretty cool carbine conversion kits for 1911 and Glock pistol made by “Mec-Tec”
The website is out of date and I do not know if the kits are still sold. I do know that in most Western countries converting a pistol into a rifle is not allowed. UPDATE: I was wrong. See comments below.
UPDATE:
Some more photos from gunbroker
I wonder how such a long barrel manages to tilt when fired without stressing the pistol too much…

0Carl, the barrel doesn’t tilt. The carbine conversion has a fixed barrel. The only parts of the pistol used are the frame assembly and magazine.
0 0Ok, I like the idea, how about a little less ugly?
0 0I have one of these for my Kimber Classic (1911) and the carbine conversion unit (CCU) makes for a great “plinker.” CCU’s maker (Mech Tech System in Montana) has updated the styling, adding as M4-style options such as collapsible stocks, “iron” sights, and Picatinny rails all along the barrel shrouds.
See their Web site:
Which should also help the poster who’s looking for help in breaking down the CCU.

The best thing would be to contact the manufacturer for a manual.
0 0Thanks Beamish for that infomation. You are right!
I was not aware pistol to rifle conversions were legal but your explanation makes complete sense.
Apparently under Californian law it is illegal:
“Although the product of itself is legal, the resulting combination with a pistol frame becomes illegal under California law” from http://www.gunbroker.com/Auction/ViewItem.asp?Item=80662811.
As far as I know in many other countries it is illegal as pistol are classified differently to rifle in the local laws.
0 0I have this conversion for a Glock 17. I was given to me after a friend passed away. I do not have any paper work for it but was wondering how you break it down?? Can you help me
0 0You cannot add a shoulder stock to a pistol without registering it as a short-barreled rifle (SBR) and paying the tax. An SBR is defined as having a barrel of less than 16″. These “Carbine kits” have 16″ barrels with the shoulder stock and so are therefore legal – you are taking a formerly “concealable” pistol and making it into a non-concealable rifle.
Going the other way – converting a rifle into a “pistol” is not permitted without further ATF taxes and approvals.
